rare case of cerebellar glioblastoma multiforme and supratentorial oligodendroglioma presenting as synchronous primary brain tumors.

Ependymoblastoma is a rare and highly malignant brain tumor considered to be a subtype of primitive neuroectodermal tumors. We presented a case of ependymoblastoma in a 14-year-old girl. CT and MRI showed a large, supratentorial, paraventricular tumor with cystic and irregularly enhancing solid components. Foci of intratumoral hemorrhage and absence of peritumoral edema were also demonstrated. ...

BACKGROUND AND PURPOSE To investigate the influence of cerebral atrophy on clinical outcome in patients with supratentorial intracerebral hemorrhage. METHODS Computed tomography scans of 320 patients included in a prospective, multicenter trial were used for a segmentation analysis to determine the supratentorial cerebral volume. A logistic regression analysis was used to explore its effect o...

The effects of discrete increases in the volume of an artificial space-occupying lesion on intracranial pressures and the systemic circulation were studied in six anaesthetised and artificially ventilated dogs. Each increase in volume, accompanied by an increase in supratentorial intracranial pressure, a decrease in supratentorial perfusion pressure, and an increase in transtentorial pressure g...

BACKGROUND The aim of this investigation was to determine the effects of diclofenac on cerebral blood flow. Middle cerebral artery blood flow velocity was measured in nine patients with supratentorial tumours. METHODS Using a transcranial Doppler ultrasound, we measured the baseline mean and systolic cerebral blood flow velocity. Measurements were repeated following administration of diclofen...

CASE PRESENTATION A 45-year-old woman with a history of seizures, headaches, nausea, vomiting, and decreased visual acuity of 5 years. Visual field detected a bitemporal heteronymous hemianopia. Magnetic resonance imaging revealed basal cistern arachnoiditis and supratentorial hydrocephalus. Cranial computed tomography revealed supratentorial calcifications, scolex in the left occipital region,...

A varix occurring with a cerebral venous angioma is a rare combination of cerebral vascular malformations. The most common vascular anomaly associated with a venous angioma is a cavernous angioma. We report a case of bilateral supratentorial venous angioma with 2 varices involving the angioma situated on the right frontotemporal region. Multiple subependymal veins were seen in the right suprate...

Intracranial anaplastic ependymomas are a very rare entity within the group of adult CNS neoplasms. Thus, no standard adjuvant therapy after surgical resection has been defined so far. External radiotherapy is commonly administered, but the role of chemotherapy is still unclear in malignant ependymomas. The case of a 25-year-old female patient with multifocal recurrence of a supratentorial mali...
